In ideal environments, most common construction materials are very durable. However, design or construction deficiencies or lack of proper maintenance can result in less-than-ideal conditions under which construction materials will degrade. Traditional construction materials, like steel, concrete, and wood, usually deteriorate and fail via well-known mechanisms. Assessing the structural health state of structure is crucial in terms of infrastructure sustainability. Among other kinds of civil infrastructure, bridges are the most susceptible to degradation. Besides always being exposed to the external environment which tends to be aggressive/corrosive, their locations are often secluded, which makes it relatively more difficult to be monitored. As part of the bridge management system, manual inspection programs and structural health monitoring (SHM) are the most important components, which will be complementary and inseparable to each other. The manual inspection program should be established, which may provide reliable basis for bridge inspection and maintenance and ensure the specific and effective management decision. The main function of the SHM for bridge reflects in validating the bridge’s design and ensuring its security, identifying the bridge’s damages in time, providing the effective messages for bridge maintenance and management, and assisting to the daily traffic management. The structural damage identification is the key issue in SHM, and could be categorized into four levels, i.e. detecting the existance of damage, finding the location of damage, estimating the extent of damage, and predicting the remaining fatigue life. This paper deals with the most recent techniques of SHM of long span bridges, Indonesian experience in implementing the structural health monitoring system at Suramadu Bridge, and the direction of future development, which apparently has to be synchronized with the development of sensor technology, computational technology, structural damage identification theories, and information technology, for the sake of infrastructure sustainability.
